Safely clean black mold or call a professional?« Back to Previous Page

We've lived here for 2 years and just noticed a patch of black, fuzzy mold spreading in the corner of our master bedroom closet, right where the outside wall is. My husband and I have both been waking up with headaches and a stuffy nose that clears up after we leave for work. I'm really worried this is the cause. **What's the safest way to clean this ourselves, or should we call a professional company right away?**

Stop using the closet and keep the door closed. Your symptoms aligning with time spent at home are a strong indicator that this mold is a likely cause.

For a patch smaller than one square meter, you can attempt to clean it yourself. Wear an N95 mask, gloves, and safety glasses. Scrub the area with a mixture of detergent and water, then disinfect with a solution of one part white vinegar to one part water. Do not use bleach, as it only removes the surface colour and can worsen indoor air quality. The key is to address the moisture source. In Dubai, this is almost always condensation from an AC supply line running inside the wall or a small leak from a pipe or external water seepage during rare rains.

Given its location on an external wall and the recurring symptoms, this is likely a persistent issue. DIY cleaning often fails because it only addresses the visible growth, not the hidden moisture problem within the wall cavity. A professional inspection is strongly recommended to identify and rectify the root cause with tools like thermal imaging and moisture meters. They can also perform air and surface sampling to confirm the mold type and ensure remediation is complete. For health-related cases like yours, this is the safest course of action.
